Coventry boss Mark Robins called on his side to start climbing the League One table after their last-gasp 1-0 victory at Oldham.
The Sky Blues snatched their first win since relegation from the Championship thanks to a 90th-minute goal from sub Cody McDonald.
Fellow strugglers Oldham created the better chances at Boundary Park, but their finishing lacked conviction and visiting keeper Joe Murphy made fine saves from Christian Montano and Matt Derbyshire.
Robins said: "It's amazing what three points can do. I'm delighted, it's a relief to get a victory and hopefully this will be the result that gets us moving forward.
"It was one of the worst games I've seen in my life. They were two anxious teams who haven't had the greatest of starts. We were fortunate because our play could have been punished at any time, but that didn't happen and the result was all that mattered.
"I could be hyper-critical. We didn't pass the ball well and, when we did get it down, we gave it away too often. But I'll take three points all day long because it breeds confidence and can get you on the front foot again.
"Oldham have some good players and we helped them to gain some impetus, so that's something we need to work on improving. But we've come away with a clean sheet and a win and our goal came from clever play by Cody to get himself into some space."
Oldham manager Paul Dickov insisted his team would soon hit winning form - but also blasted their defensive frailty.
Dickov said: "It was an unacceptable goal to concede and we aren't keeping enough clean sheets. The warning signs had been there a few minutes earlier, but we still allowed the cross to come in and we still gave their player room inside our box.
"I'm talking about basic defending and we work on these things every day, so we need to take them into games. I'm not stupid and I know we need results, but I also know that that's going to start happening."
